Abstract: A radiofrequency harvester circuit may be used in a battery-less RFID device. The harvester circuit includes an antenna unit that captures radiofrequency signals and harvesting circuitry coupled to the antenna unit for collecting energy from the radiofrequency signals captured by the antenna unit. The antenna unit is selectively tunable at a plurality of tuning bands that are scanned by selectively tuning the antenna unit at different frequency bands and sensing respective values indicative of the power of radiofrequency signals captured by the antenna unit at the frequency bands scanned. A highest value out of said respective values for the power of radiofrequency signals as well as the frequency band in the plurality of tuning bands of the antenna unit providing the aforesaid highest value are identified and the harvester circuit is operated with the antenna unit tuned at the frequency band providing the highest value thus identified.

Abstract: A microscope for imaging a sample is disclosed that includes an illumination objective arranged to eject an illumination light beam along an illumination path to illuminate the sample. A further illumination objective is arranged to eject a further illumination light beam along a further illumination path wherein the further illumination objective is arranged to eject the further illumination light beam substantially opposite to the illumination light beam. An imaging objective is arranged to receive detection light that is propagated along a detection axis to the illumination path and further illumination path. A sample holder is placed above the imaging objective and arranged to receive a sample. A holder support is arranged to receive the sample holder and to displace it relative to the imaging objective along three perpendicular axes and/or to rotate it around at least one rotation axis. The sample holder contains a separation wall creating linearly arranged compartments.
